The invention relates to the technical field of fire hydrants, and discloses an anti-freezing and convenient-to-detect fire hydrant which comprises a fire hydrant body, a rotary valve, a rotary rod and a water inlet pipe. By designing an inflation inlet, an air bag, a blocking plug, a water return hole, a water return pipe, a thermistor, an electromagnetic block, an air cavity, a magnetic plate and a compressed spring, when the fire hydrant needs to be subjected to water drainage and freezing prevention in winter, the air bag in the fire hydrant body is inflated through the inflation inlet, the air bag drives the blocking plug to move downwards, and water flow is extruded into a water inlet pipe through the water return hole and the water return pipe; as the aperture of an air hole is smaller than that of an air groove, the air pushes a magnetic plate to move downwards and promotes a compressed spring on the lower side of the magnetic plate to store energy, the magnetic plate is promoted to move up and down in the air cavity, an electromagnetic effect is generated between the magnetic plate and a coil, current is generated, the magnetic block is adsorbed by increasing the magnetic force of an electromagnetic block, and a blocking plug is promoted to be fixed; the interior of the fire hydrant is prevented from being frozen due to low temperature in winter.
本发明涉及消防栓技术领域，且公开了一种防冻且便于检测的消防栓，包括消防栓本体、转阀、转杆和进水管。本发明通过设计充气口、气囊、挡塞、回水孔、回水管、热敏电阻、电磁块、气腔、磁板和压簧，通过冬季需对消防栓进行排水防冻时，利用充气口对消防栓本体内部的气囊进行充气，通过气囊带动挡塞下移将水流经回水孔和回水管挤压进入进水管内，气体先进入气腔由于气孔的孔径小于气槽的孔径，使得气体推动磁板下移并促使磁板下侧的压簧蓄能，促使磁板在气腔内部上下移动，使得磁板与线圈之间发生电磁效应并产生电流，通过电磁块的磁力增大对磁块进行吸附，促使挡塞固定，防止因冬季气温低造成消防栓内部被冻。
